1. A loaded perforating gun positionable in a wellbore penetrating a subterranean formation, the loaded perforating gun comprising:
a gun housing;
a detonator assembly positioned in the gun housing, the detonator assembly comprising a detonator and a detonation switch; and
a plunging charge assembly positioned in the gun housing, the plunging charge assembly comprising:
a charge tube,
a shaped charge supported in the charge tube, and
a plunger comprising a receiving cap and a detonator cord, the receiving cap connected to the charge tube, the detonator cord supported in the receiving cap, the shaped charge operatively connected to the detonator cord;
wherein the plunging charge assembly is selectively movable between a disarmed position with the detonator cord disconnected from the detonator assembly and an armed position with the detonator cord operatively connected to the detonator of the detonator assembly whereby the detonator can selectively pass a detonation signal to the shaped charge; and
wherein the plunger further comprises a compression mechanism.
